When processes that are spontaneous in nature are accelerated by man, they can endanger biosphere, therefore it is necessary to put them under control to prevent further environmental pollution. By the means of microbial leaching solutions, in the case when the type of ore and the geological characteristics of the soil are suitable, it is possible to recover certain metals with minimum investment and threats to environment. It is usually utilized when conventional mining procedures are too expensive or ineffective in recovering a metal such as copper, gold, lead, nickel and zinc. On the one hand, contamination of ground water and soil by heavy metals is prevented, on the other hand extraction of precious metals from ore dumps and from low-grade ore are occurring. At present, numerous facilities for microbial leaching are in use not only in developed countries, but also in developing countries. This paper presents overview of present achievements in biohydrometallurgy, as well a reminder that this technology was successfully used in our country for short period of time.
